Title: System and method for wireless communication, and transmitter and receiver
Inventor: SUGITA TAKEHIRO
IPC: H04B1/40
Filed: 2003-03-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve a transmission speed with a relatively low C/N by using a plurality of antennas and modulator/demodulators.  <P>SOLUTION: The m pieces of transmission blocks 32a-32m of a transmitter execute the wireless transmission of data by having the same time with the same frequency from each transmission antenna in common together with reference signals peculiar to each transmission block. Each of n (n≥m) reception blocks 42a-42n of a receiver detects the reference signals S1-Sm transmitted from the transmission antennas on the basis of signals received by the reception antennas. It calculates the value of a matrix comprising a plurality of elements which show extents of contributions of the signals transmitted from a plurality of the transmission antennas to the signals received by each reception antenna on the basis of the detected reference signals. A reception signal separator 45 separates signal components transmitted by a plurality of the transmission blocks from the received signals of a plurality of the reception blocks on the basis of the calculated value of the matrix. A demodulator 47 demodulates them.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
